- Guttering that needs replacing
- Blocked downpipes

Gutter sealing in Black Bourton, done properly
We don’t replace gutters, fascias or roofs. What sealant does is close joints and it cannot mend broken brackets, split sections or blocked downpipes. If you’re dealing with end caps that drip every time it rains and rain getting in around a garage door, we can help, on gutter end caps, gutter joints and roofline trims alike.
In a village or hamlet like Black Bourton, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
You get a one-year guarantee, the same in Black Bourton as everywhere else we work.

How we quote for gutter sealing
Jobs vary more than people expect. What affects the quote:
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- When we can work, for business premises
- Which sealant suits the joint
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Whether it has been sealed before
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
- How we’d reach the joints
Every job is quoted individually, so start by telling us what you need. Simply ring 0345 464 0079 or email us and describe the job, and pictures are welcome.
Gutter sealing in Black Bourton: local notes
Historic houses like Kelmscott Manor (about 4.2 miles south-west) are a reminder that the area around Black Bourton has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as St Peter's Church of England School, larger buildings have long runs of movement joint that eventually need resealing. For an older house near a landmark such as Church of St Mary the Virgin, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Why act early in Black Bourton
Replacing fascias because of open joints is generally unnecessary. A neat seal closes the gaps as long as the boards are in good condition. In a small place like Black Bourton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

What happens on the day
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from an hour or two to a few hours. For a village or hamlet like Black Bourton, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, we find the drip and check the gutter is not cracked or sagging.
- We clean out the joint and take out the old sealant.
- The area is dried so the sealant can bond.
- An exterior or gutter sealant is applied to the joint.
- The run is checked and any debris near the joints is cleared.

Do you take out the old sealant first?

Different surfaces, different methods
uPVC fascias
Fascia board joints can open up. They’re sealed tidily with a matching sealant where possible.
Gutter joints
Joints between gutter lengths are the most common leak point. We clean, dry and reseal them.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
